I currently building a UV transilluminatorbased on your previous design. Can you tell me where to source to proper UV transmitting diffusion material? Thanks.
Wow. I would like to apologize for me poor sentence structure and word spacing on my original query. I was on mobile, and apparently have very fat fingers and proof reading skills.
So, for the diffuser we used Solacryl, which is a clear UV-transmissive acrylic (1/8" thick). We then use a hand-held sander to sand both sides of the material. After sanding, give the materail a rinse in water and this makes a pretty good UV-transmissive diffuser.
You can search online for Solacryl material. In my experience it is not that expensive, but you will have to buy a sheet and cut it to the size you need. We have bought our Solacryl sheets from a company called Loop Acrylics in the US. You can contact them by email at email@example.com. I hope that helps !
Outstanding! That is pretty close to what I wanted to do.
